Will add my anecdotal evidence: I've seen this across the board from Microsoft. I've been a customer for several decades, and it is a bit of a nightmare now.

Logins that redirect to odd places. Jolting issues because you changed a seemingly innocuous security setting (i.e. OneNote refuses to sync on specific versions of the app/software if you don't grant them full access). Or just inconveniences, like having to login multiple times across their own sites when I dive into Office settings management. Seemingly forced use of the Microsoft Authenticator app from time to time.

Multiple computers, multiple devices. I can usually work around it, but it is a pain.
